👋 Hello! Before merging this PR, you can use the run-gds label to start the GDS workflow.

⚠️ Important: The GDS workflow takes a long time (~1 hour) and consumes significant CI runtime quota.

Before running the GDS workflow:

1. Make sure you've run the hardening command locally first:

   ./tt/tt_tool.py --harden

2. Verify that the hardening command succeeded without errors

To run the GDS workflow:

• Add the run-gds label to this PR
• The workflow will run automatically
• It will also re-run on subsequent pushes while the label remains attached

📚 For more information about the hardening command, see the TinyTapeout GDS Action.
